We use g-suite and use the old google hangouts. In an attempt to try out the new "Hangouts Chat" Most of the employees appear as 'Anonymous User' to everyone else. Only a tiny handful of employees appear as their actual name. This occurs even in direct 1:1 conversations.

Anyone have a solution to this?

edit:
While comparing the employees that appear correctly vs "Anonymous User" we noticed anyone who enabled Google+ showed up correctly. Not a solution in our view since we can't force (nor do we want to) folks to enable social media.
